Anchor refractory bricks, also known as hanging bricks, are a type of refractory material used in industrial kilns. They are made by selecting high-quality raw materials, forming them through machine pressing or casting, and then sintering at high temperatures. Anchor bricks can be roughly divided into two types based on the material used: high-alumina and clay.

High-strength alkali-resistant bricks
Alkali-resistant bricks are generally made from low-alumina clay bricks with an Al₂O₃ content of 25-30%, and are produced by adding silica, corundum, and a suitable amount of additives to improve compressive strength.

Magnesium-aluminum spinel brick
Magnesium-aluminate spinel bricks are alkaline refractory materials primarily composed of periclase and spinel, formed through high-pressure molding and high-temperature sintering, while also adding excellent fluxing agents to ensure direct bonding between the crystalline phase particles of the product.

Magnesium iron spinel bricks are a new generation of chromium-free alkaline refractory materials used in the firing zone of large rotary kilns. They utilize the characteristic of iron oxide solidifying in magnesium oxide, using high-purity spinel as raw material, and are formed into chromium-free and environmentally friendly products through high-temperature sintering.

Mullite aggregate lightweight brick / Mullite lightweight insulation brick
Mullite-type lightweight bricks have low thermal conductivity, good thermal insulation and heat preservation effects, and can withstand temperatures above 1500℃.
View Details
Magnesia-chrome bricks are refractory material products mainly composed of magnesium oxide (MgO) and chromium trioxide (Cr₂O₃), with periclase and spinel as the main mineral components.
